Mesa Boogie Mark V 3-Channel 90-Watt Guitar Head Maple Enclosure

The Mesa Boogie Mark V is a three-channel, all-tube command center that distills over 40 years of Mark Series innovation into one tone-sculpting monster. Featuring switchable 90/45/10-watt operation, a fully independent 3-channel layout, and 5-band Graphic EQ, the Mark V is a Swiss Army knife for serious players. This example—serial MKV-002500—comes wrapped in a striking Natural Maple hardwood enclosure, blending boutique looks with high-octane flexibility. From lush clean tones and gritty mid-gain crunch to tight, modern saturation, the Mark V is pure Boogie precision at its finest.
